Figure 2.
Bioluminescence (photons/sec) was quantified for individual animals at all time points. Stable levels of bioluminescence were observed through 21 months as noted. AAV9 showed high, transient expression of firefly luciferase up to 2 months postnatal age. Mean levels of bioluminescence for animals in each group (n = 2 for AAV9, n = 4 for AAV2i8) are shown (standard error bars for AAV2i8).
